Communications Clock PLL

Description

Features

• Packaged in 20 pin SOIC

The MK2049 is a Phase-Locked Loop (PLL) based

clock synthesizer, which accepts an 8 kHz clock

input as a reference and generates T1, E1, T3, E3,

and OC3 frequencies. The device can also accept a

T1, E1, T3, or E3 input clock and provide the

same output for loop timing. All outputs are

frequency locked together and to the input. This

allows for the generation of locked clocks to an

8 kHz backplane clock, simplifying clock

• Meets the TR62411, ETS300 011, and GR-1244

specification for MTIE, Pull-in/Hold-in Range,

Phase Transients, and Jitter Generation for

Stratum 3, 4, and 4E

• Accepts multiple inputs: 8 kHz backplane clock or

Loop Timing frequencies

distribution in communications systems.

• Locks to 8 kHz ±100 ppm (External mode)

• Exact internal ratios eliminate the need for external

dividers

MicroClock can customize this device for many

other different frequencies. Contact your

MicroClock representative for more details.

• Zero ppm synthesis error in all output clocks.

• Output clock rates include T1, E1, T3, E3, and

OC3÷8

For a fixed input-output phase relationship, refer

to the MK2049-02, -03, or -3x. The MK2049-3x

are 3.3 V devices.

• 5 V ±5% operation

• Offered in Commercial and Industrial temperature

versions
